Yet, because the cars are relativelysound to begin with, few warrantyclaims arise, so the company makes asolid profit on the warranties.Consequently, salespeople areencouraged to sell the warranties andreceive a relatively high 25 percentcommission on them. As shown inFigure 3, separate warranties areoffered for various components. Forinstance, an exterior warranty coversthe paint, while a drive-train warrantycovers various engine and transmission elements. Note that each warranty only covers thelisted items. Customers are given several options, including the length of the warranty andthe level of the deductible. Of course, longer warranties and lower deductibles cost more.These values are specified in the warranty policies, but the salesperson needs to enter themon this form so everyone knows exactly which warranty was purchased. The customer alsohas the option of paying the warranty fees upfront as a lump sum, but most decide tofinance them over time in the form of monthly payments. These values are entered by thesalesperson using a chart—essentially the company charges a one percent per monthinterest rate for financing the warranty costs.Start4
